Abstract

A positioning device has a shaft (1) which can swivel relative to a housing (7), a rolling bearing unit (4) for mounting the shaft (1) relative to the housing (7), and a swivel drive (2) comprising a stator and a\ rotor. The shaft (1) is arranged axially movable and rotationally rigid via an annular membrane (6) which is fixed relative to the housing and is fixed on the rolling-bearing unit (4).
